Abuse and greed by Living Link and landlord

I rented a property with Eldu properties in 2021, in the Middle of that lease agreement Living Link Realty took over.

At the end my lease this year I decided not to renew due to high cost of electricity.

Upon Vacating the apartment i was advise the to paint the whole apartment as the landlord wanted the place to its original state.

Even though I didn't quite agree with this, knowing thst I had kept the place clean I agreed. I must add that as I should i also sent someone to clean the apartment. To prove how we'll I kept the place the agent even wrote a beautiful recommendation for me to another agent which I'm willing to share, now they have decided to keep over 7k deposit for non existent damages. I find this conduct cruel and abusive ss a tenant.
